DC04 - Kub dov hlau
DC04 yog ib qho qis - carbon steel uas zoo siab nrog nws qhov tshwj xeeb txias formability. Cov tshuaj muaj pes tsawg leeg ntawm DC04 yog qhov sib npaug los xyuas kom meej tias cov khoom muaj qhov xav tau cov khoom siv kho tshuab. Cov ntsiab lus carbon hauv DC04 feem ntau yog qhov siab tshaj plaws ntawm 0.08%, thaum cov ntsiab lus manganese yog qhov siab tshaj plaws ntawm 0.40%. Qhov no muaj pes tsawg leeg txhawb lub siab formability thiab weldability ntawm cov hlau, ua rau nws zoo tagnrho rau kev thov kev tsim cov txheej txheem.

DIN EN 10130 tus qauv kuj tseem qhia txog qhov kam rau ua rau qhov ntev, cov duab thiab qhov chaw tiav. Cov kev tolerances no yog ib qho tseem ceeb los xyuas kom meej cov khoom zoo tsis tu ncua thiab ua kom tau raws li cov neeg siv khoom kawg. Qhov saum npoo ntawm cov khaub thuas- dov ca cov khoom tuaj yeem muab rau hauv ntau yam zoo, los ntawm matt mus rau siab -gloss, kom ua tau raws li cov kev cai tshwj xeeb ntawm kev siv sib txawv.
Cov khoom siv kho tshuab ntawm DC04 yog tus cwj pwm los ntawm lub zog qis ntawm qhov siab tshaj 210 MPa thiab lub zog tensile ntawm 270 thiab 350 MPa. Tshwj xeeb tshaj yog tsim nyog yog qhov siab elongation ntawm kev tawg yam tsawg 38%, uas qhia txog qhov zoo heev formability ntawm cov khoom. Cov khoom no ua rau DC04 qhov kev xaiv zoo tshaj plaws rau kev tsim cov khoom sib txuas uas yuav tsum tau muaj kev ua haujlwm siab thiab qhov zoo, xws li cov khoom siv lub cev hauv tsheb hauv kev lag luam tsheb lossis filigree qhov chaw hauv kev lag luam hluav taws xob.
